Abstract :
The discrete wavelet transform (DWT) being applied to the spectrum analysis algorithm in an automatic frequency control (AFC) feedback loop, the AFC has an intelligent characteristic of “observation and control according to frequency error”, which makes it possible to achieve both fast initial acquisition and accurate tracking. Furthermore, it can make the irreducible frequency error arbitrarily small; the longer it operates, the smaller the frequency error becomes
